Rudders are primary steering devices for merchant ships. The main purpose of using
rudders is to generate forces for course keeping and manoeuvring. In exceptional cases …

The proper evaluation of the Rudder–Propeller interactions is mandatory to correctly predict
the manoeuvring capability of a modern ship, in particular considering the commonly …

The hull-propeller-rudder interaction of a twin-screw ship is investigated by using CFD
method. The hydrodynamic performances of propeller and rudder during maneuvers are …

The maneuverability performance of a KCS with energy-saving devices was investigated. A
bulb-type wavy rudder and an asymmetric pre-swirl stator were used as energy-saving …

A novel collaborative spoiler rudder (CSR) is proposed to improve the maneuverability of a
ship. This work focuses on the hydrodynamic performance of CSR in two-dimensional …

ABSTRACT RANS simulations are implemented to analyse the hydrodynamic
characteristics of twin-rudders, ie Flat plate rudders, NACA rudders, and Wedge-tail rudders …

This study presents the hydrodynamic performance estimation of a collaborative spoiled
rudder (CSR)-a new concept of ship rudder under open water conditions. The grid sensitivity …

Meshing is one of the crucial key features to the success of CFD based simulations, this
study is evaluating the efficiency of polyhedral elements in solving the problem of the flow …

To achieve energy conservation and improve ship maneuverability, a new type of
collaborative spoiled rudder (CSR) is proposed by absorbing the advantages of existing …

Conventional rudders do not provide adequate manoeuvrability for some ships. Such ships
may have unconventional rudders. This chapter describes the special features of these …
